Niwot Neighbors Promoting The Needs Of Our Community

Sue Hirschfeld, a retired geologist and Boulder County Volunteer Naturalist, conducted an informative guided tour of the Foxhill Sandstone formation that is exposed on the Hillside Estates Open Space in Niwot. This exposure of the Fox Hills sandstone, on which Sue has been conducting research, is a very special area geologically and botanically, containing both fossils from when this area was a shallow sea and, presently, several rare or endangered species. Some of the highlights include shark’s teeth, ophiomorphas, miner bees, and rare lichens.

A special thanks to Sue for leading this tour, and to Craig Rahenkamp (Area #2 representative) for organizing the event for the NCA.
